politicians are asking whether scotland yard's links to the paper stop police probing the phone- hacking scandal more deeply. full disclosure is embarrassing too for the prime minister. a list of engagements released by downing street today show just how frequently he paid court to news corp. executives and they to him. the prime minister won't be saying sorry for that, but rupert murdoch will be apologizing again this weekend for what he called serious wrongdoing at the "news of the world." he's personally signed a letter, which will run as an advert in seven national newspapers so his later in the day, a second top murdoch executive resigned. since 2007, les hinton has been c.e.o. at dow jones and company, publisher of the "wall street journal." but for 12 years, he chaired the company that oversaw the british tabloids now involved in the scandal. he said in a statement today he was ignorant of what apparently happened, but felt it proper to resign. for more on that part of the story, i'm joined now by rem reider of "american journalism review." thanks for being with us. >> my pleasure
